Calculating CO2 Emissions from Mobile Sources

This guidance is intended to facilitate corporate-level measurement and reporting of greenhouse gases (GHG) emissions from transportation and other mobile sources.

This tool is included in the Transportation Toolkit from the LEDS Global Partnership.

When to Use This Tool

While building a low emission strategy for your country's transportation system, this tool is most useful during these key phases of the process:

• Create Baseline - Developing a business-as-usual scenario

• Develop Alternatives - Building and assessing alternative scenarios

• Implement & Monitor - Launching low-carbon transport systems and measuring their impact

Learn more about the key actions you need to take to build a successful LEDS.

How to Use This Tool

"This guidance is intended to facilitate corporate-level measurement and reporting of greenhouse gases (GHG) emissions from transportation and other mobile sources. The section addresses direct GHG emissions from owned or controlled mobile sources and indirect emissions from the use of transportation sources that are owned or controlled by other entities. In this tool the following categories of mobile sources are covered:

• Road transport
• Rail transport
• Air transport
• Water transport

This is a cross-sectoral guideline which should be applied by all industry and service sectors whose operations involve the combustion of fossil fuel in mobile sources or the purchase of freight and/or travel services."
